AcceleratingObjectLocator - Structural Model

Goal: Design an accelerating object locator that implements the following equation:

Locator Controller & Datapath:

FSM Model:

Constants

• Zero Constant, stored in regArray(0)
• Constant acceleration (a): 11 m/s2 (meters per second squared), stored in regArray(1)
• Time (t): 8 seconds, stored in regArray(2)
• An initial velocity (v0): 3 m/s (meters per second), stored in regArray(3)
• Starting location (x0): 5 m (meters), stored in regArray(4)
• regArray(5) through regArray(7) are free slots

Clock cycle calculations

Logical Component Delays:

• State Register (StateReg): 4 ns from Clk to output, 1 ns setup time
• 8×16 Register File (RegFile): 6 ns from input to output (reading), 6 ns from Clk to output (writing), 1 ns setup time (writing)
• ALU (ALU): 12 ns from input to output
• 16-bit Shifter: 4 ns from input to output
• 2-to-1 Selector: 3 ns from input to output
• 16-bit Output Register (OutReg): 4 ns from Clk to output; 1 ns setup time
• 16-bit Three-state Buffer (ThreeStateBuff): 2 ns from input to output

Minimum clock cycle = StateReg + CombLogic¹ + RegFile + ALU + Selector
= (4 + 1) + 11 + (6 + 6 + 1) + 12 + 3 = 44 ns

1: Combinational Logic Delay(CombLogic): 11 ns
